Finding a resource in response to a query including unknown words

ABSTRACT

A computer receives a search query from a user for finding a resource. The computer extracts one or more words from the search query using morphological analysis. The computer assigns at least one first category to at least one first word of the one or more words using a dictionary. In response to identifying an unknown word not in the dictionary within the one or more words, the computer searches for the unknown word on a net. If the unknown word is found on the net, the computer obtains a description on a page on the net on which the unknown word is found, extracts one or more second words from the description using morphological analysis, assigns, using the dictionary, at least one second category to the one or more second words extracted from the description, finds, among the one or more second words, a particular word to which a predetermined category was assigned, extracts a correlation word from among the one or more second words having a high correlation with the found particular word, and finds, among the first words, a search word assigned the at least one first category that is the same as the predetermined category, finds, from a repository, resource data or worksite data using the correlation word and the search word, and lists the found resource data.

Hereinafter, the various embodiments of the present invention will be described with reference to the following FIGS. 2A to 2C, FIGS. 3A and 3B, FIGS. 4A and 4B, FIGS. 5A to 5C, FIGS. 6A and 6B, FIGS. 7A to 7C, FIGS. 8A and 8B, FIGS. 9A and 9B, and FIG. 10.

An embodiment of the present invention is based on the following perceptions. Chatbots used by employment agencies for dispatching human resources have a problem in that, if a search query includes an unknown word, the chatbots may answer to the search query as follows: “a meaning of the search query cannot be understand” or “No human resource is found”, or the chatbots may answer the search query using words in the search query other than the unknown word, because the dictionary used by the chatbot to parse the words of the query has no such unknown word. This may cause a case that no human resource is presented on the display to the user in response to a search query. To avoid this problem, an advantage of one or more embodiments of invention, is the chatbot may find an unknown word using not only the dictionary, but also by searching on a net or on a repository for storing one or more types of resource data, including, but not limited to, human resource data, machine resource data, worksite data for a human resource, and worksite data for a machine resource.

FIGS. 2A to 2C and FIGS. 3A to 3D each illustrate a block diagram depicting examples of a computer-implemented method for finding “a human resource” and “a machine resource”, respectively.

With reference now to FIGS. 2A to 2C, FIGS. 2A to 2C illustrate a block diagram depicting examples of a computer-implemented method for finding “a human resource”, in accordance with an embodiment of the present invention.

With reference now to FIG. 2A, FIG. 2A illustrates a display 201, displaying a conversation between a user and a computer system according to an embodiment of the present invention. The user may be a person who wants to find a human resource using the computer system. The computer system may correspond to computer system 101 described in FIG. 1.

Display 201 may be connected to computer system 101 through a display cable or a separate computer to which display 201 is connected. The separate computer may be connected to computer system 101 via a network, such as, but not limited to, an internet or an intranet.

First, the computer system may display, on display 201, a message prompting input of a search query for finding a human resource. For example, the message prompting input of a search query as displayed in balloon 211 is as follows: “We will present human resources in technical fields to you. What type of human resources are you searching for?”

In response to the display of the message in balloon 211, the user may input, using one or more types of input interfaces, including, but not limited to, a keyboard, a mouse, a touch pen or a finger of the user, or speech input method, a search query for finding a human resource. The search query may be an input in a natural language form. For example, the search query input in a natural language form from the user as displayed in balloon 212 is as follows: “Human resources having a capability for cases related to a soft development of Projection TTTYYY.”

In response to the input of the search query from the user illustrated in balloon 212, the computer system receives the search query from the user.

One example of the received search query is illustrated in block 221 as follows: “Human resources having a capability for cases related to a soft development of Projection TTTYYY.”

The computer system extracts words from the search query illustrated in block 221 using morphological analysis. In one example, by using morphological analysis, the computer system may cut out words and carry out parsing in a received search query. It will be apparent to one skilled in the art that any known computer-implemented methods for morphological analysis can be used for extracting words from the search query. It will be apparent to one skilled in the art that one or more different types of analysis may be implemented to extract words from search queries in one or more different types of forms.

Block 222 shows an example of the extraction of words from the search query. Block 222 shows that the extracted words are as follows: “human resources”, “capability”, “cases”, “related to”, “soft development”, and “Projection TTTYYY”.

After the extraction of the words from the search query, the computer system assigns categories to the words using a dictionary 261. In one example, the one or more extracted words to which categories have been assigned in block 223 may be referred to as “first words”. In one example, the categories in dictionary 261 may include, but are not limited to, a category representing a skill of a human resource, a category representing that a word relates to a question in a search query, or a category representing a part of speech.

In one example, the computer system may use dictionary 261 as a keyword dictionary, as explained below.

The keyword dictionary may comprise pairs of word and a category associated with this word. Words in the keyword dictionary may be words relating to the finding of a human resource, such as common or specific words used in search queries. Categories in the keyword dictionary may be categories which can be assigned to a skill word or an inquiry word in words extracted from the search query.

An embodiment of a keyword dictionary is shown in FIG. 8A. A keyword dictionary 801 comprises pairs of word and a category associated with this word. The categories shown in keyword dictionary 801 are “skill” and “inquiry”. The category “skill” indicates that a word assigned to this category relates to a skill for a human resource or a machine resource, or a skill to be required for finding a human resource or a machine resource, or a skill to be required for finding a worksite for finding a human resource or a machine resource. The category “inquiry” indicates that a word assigned to this category relates to an inquiry word but not relates to a skill word.

The keyword dictionary may have a synonym for a word in the keyword dictionary. A synonym may be an additional word having the same or nearly the same meaning of the original word.

An example of a synonym is shown in keyword dictionary 801. Keyword dictionary 801 shows that a synonym of “soft development” is a word “software development”.

If a particular word in the extracted words in block 222 from the search query is listed, as a synonym, in dictionary 261, such as keyword dictionary 801, the computer system may find a synonym of this particular extracted word from the search query and then replace this particular extracted word from the search query with the found synonym, because the found synonym is commonly listed in dictionary 261 or commonly used compared to the extracted word from the search query. In another embodiment of such replacement, if an extraction dictionary applied for morphological analysis has a synonym, the computer system may replace this particular extracted word from the search query with the found synonym in the process of the morphological analysis, using the extraction dictionary (not shown) used in the morphological analysis.

If a word among the extracted words in block 222 is not found in dictionary 261, the computer system may assign a category “unknown word” to this word. Alternatively, the computer system may not assign any category to this word. In this alternative embodiment, any category is not assigned to this word.

In one example, block 223 illustrates an assignment of categories to the extracted words in block 222, shown as follows: “human resources”—“inquiry”; “capability”—“inquiry”; “cases”—“inquiry”; “related to”—“inquiry”; “software development”—“skill”; and “Projection TTTYYY”—“unknown word”. In the example in block 223, the category “unknown word” was assigned to the word “Projection TTTYYY”, because dictionary 261 does not include the word “Projection TTTYYY”.

The computer system examines whether there is an unknown word in the extracted words or not. If the word to which a category “unknown word” was assigned is found, the computer system chooses this word as an unknown word 224. Alternatively, if the computer system finds a word to which any category was not assigned, the computer system chooses this word as unknown word 224.

With reference now to FIG. 2B, in one example, the computer system may search for an unknown word 226 on a net 281. Net 281 may be a network such as an internet or an intranet. The computer system may use a dictionary on the net, such as internet dictionary or an intranet dictionary.

If unknown word 226 is found on net 281, the computer system may obtain a description on a page on the net on which page the unknown word is found, as seen in a found page 282 shown in FIG. 2B. Page 282 may have a header and a description. The header may comprise a title. The description may be explanatory notes on the header. Page 282 shows the header as a title of the descriptions and a description relating to the title, as similar with a dictionary having a title and a description relating to the title. Page 282 may have the title “Projection TTTYYY” and the description “The game machine sold by ZZZ whose head quarters reside in Tokyo.”

The computer system may extract words from the description in page 282 using the aforesaid morphological analysis.

Block 228 illustrates one example of the extraction of words from the description in page 282. Block 228 shows that the extracted words are as follows: “game machine”, “sold by” “ZZZ”, “head quarters”, “reside” and “Tokyo”.

After extracting the words from the description, where the extracted words from the description may be referred to as “second words”, the computer system assigns categories to the second words using a dictionary 262.

For dictionary 262, the computer system may use dictionary 261, such as the aforesaid keyword dictionary, a system dictionary as explained below, or a combination thereof.

The previous explanation of the keyword dictionary is applicable here.

The system dictionary may comprise pairs of a word and a category associated with this word. Words in the system dictionary may be any word which may be listed on, for example, a language dictionary. Categories in the system dictionary may be categories which can be assigned to, for example, a noun, a proper noun or a verb in words extracted from the description.

One example of a system dictionary is shown in FIG. 8A. A system dictionary 802 comprises pairs of word and a category associated with this word. The categories shown in system dictionary 802 are, for example, “noun”, “proper noun” and “verb” and so on.

The system dictionary may have a synonym for a word in the system. A synonym may be an additional word having the same or nearly the same meaning of the original word.

One example of a synonym is shown in keyword dictionary 801. System dictionary 802 shows that a synonym of “soft development” is a word “software development” and a synonym of “tech questions” is a word “technical questions”.

If a word extracted from the description in block 228 is listed, as a synonym, in dictionary 262, such as keyword dictionary 802, the computer system may replace the word in extracted from the description in block 228 with a word corresponding to the synonym. This is because the replaced word is commonly listed in dictionary 262 or commonly used compared to the synonym.

An embodiment of the assignment of categories is shown in block 229 as follows: “game machine”—“skill”, “ZZZ”—“proper noun”, “head quarters”—“noun”, and “Tokyo”—“proper noun”.

With reference now to FIG. 2C, the computer system finds, among the second words in block 229, a word to which a predetermined category was assigned. The predetermined category may be determined depending on the purpose of the finding of resources. The predetermined category may be a category representing a skill of a human resource.

Let us suppose that the predetermined category is “skill”. In this case, the word “game machine” is chosen among the second words in block 229.

Thereafter, the computer system extracts a word, which may be referred to as a “correlation word”, having a high correlation with the found word. The correlation may be indicated as a correlation value. The correlation value may be a measure which indicates the degree of strength of relationship of the facet value with a document set selected by the current query in comparison with the other documents in the collection.

A correlation value may be calculated, for example, as seen in FIG. 10.

With reference now to FIG. 10, FIG. 10 shows one example of how to calculate a correlation value.

For example, as illustrated at reference numeral 1001, a correlation value=Actual measurement value/Expectation value.

$\frac{\#\left( {A\bigcap B} \right)}{\# A \times \#{B \div \#}D} = \frac{\#{\left( {A\bigcap B} \right) \div \#}D}{\left( {\# A \times \# D} \right) \times \left( {\#{B \div \#}D} \right)}$

wherein an actual measurement value is a probability of document that contains both A and B and represented as follow:

$\frac{\#\left( {A\bigcap B} \right)}{\# D};$ and

an expectation value is a value obtained by multiplying the probability of document that contains A and the probability of document that contains B together and represented as follows:

$\frac{\# A}{\# D} \times \frac{\# B}{\# D}$

With reference now back to FIG. 2C, the correlation word of the word “game machine” is “game programming” according to the correlation value as seen in a block 291. Accordingly, the computer system regards the word “game programming” as a correlation word in a block 231. Multiple words can be chosen as correlation words.

The computer system may find, among the first words, a word to which a category that is the same as the aforesaid predetermined category was assigned, wherein the word may be referred to as “a search word” in table 231. Multiple words may be chosen as search words.

In one example, illustrated in FIG. 2C, the predetermined category is “skill”. In this example, the word “software development” is chosen among the first words in block 223.

Thereafter, the computer system finds, from a repository such as human resource database (DB) 271, human resource data using the correlation word “game programming” and the search word “software development” in block 231. The computer system may find human resource data using only the correlation word, only the search word or both of the correlation word and the search word and, then, may give priority to each found human resource data using a mining method as described below.

Human resource database 271 may have pairs of an ID of a human resource (ID), status of the human resource (Status), experience level of the human resource (Experience), an available or preferable working location of the human resource (Location), and career information on the human resource (Career). The status may be represented as follows: 1. Dispatched; 2. Waiting for being dispatched; and 3. Retired. The experience level may be represented as follows: 20, 30, 40, 50, and 60. The location may be represented by one or more location identifiers, such as, but not limited to, a state name, a prefecture name, and a county name. The career information may comprise, for example, but not limited to, job history, an employment record, certificate, educational back ground, major field of study, or a qualification. In additional or alternate examples, ID, status, experience, location and career may include additional or alternate types of information and may be represented by additional or alternate types of representations.

As a result, the computer system obtains one or more human resource data entries from among the entries illustrated at reference numeral 272, from human resource data 271, with or without a value such as a recommended value or a mining analysis value.

When the computer system obtains machine resource data, the computer system may further use a mining method using a correlation related to experience level.

An embodiment of the correlation related to experience level is explained by referring to FIG. 8B.

With reference now to FIG. 8B, table 811 shows the total number of cases in which the numbers for each experience level are summed up. In one example, table 812 shows career field contains both “game machine (skill)” and “software development (skill)”. In one example, the correlation related to experience level in table 812 is calculated as follows: the ratio of assumed numerical value and an actual numerical value calculated based on the entire ratio. In the example, the aforesaid correlation related to experience level in table 812 is as follows: 50/100×(1000/4000)=2.0

The computer system may give higher priority to the word having a high score. Accordingly, if multiple words are obtained, the order of the words may be sorted according to the priority.

An embodiment of the obtained human resource data is shown in box 232 as follows: “Prefix XXX” ( %); “Prefix YYY” ( %); . . . ”.

Thereafter, the computer system or the display presents the found human resource data to the user, as seen in a balloon 213. In one example, balloon 213 is illustrated as follows:

“The following persons are recommended:

Prefix XXX ( %)

Prefix YYY ( %)

-   -   . . . ”.

The computer system may list the found human resource data according to the order of priority. Thereafter, the computer system may present the listed human resource data to the user. Alternatively, the display displays the listed human resource data to the user.

If the user wants to know more details about the presented human resource, the user can click the characters of the presented in human resource data on display 203.

In response to the click, the computer system may obtain detailed information on the presented human resource data from human resource database 271 in order to display the information on display 203.

According to the block diagram described in FIGS. 2A to 2C, an advantage of one or more embodiments of the present invention is that the computer system may the aforesaid correlation word instead of an unknown word and, therefore, may present a suitable human resource in response to a natural language input that even contains one or more unknown words.

With reference now to FIGS. 3A to 3D, FIGS. 3A to 3D illustrate a block diagram depicting a computer-implemented method of finding a machine resource, in accordance with an embodiment of the present invention.

With reference now to FIG. 3A, FIG. 3A illustrates a display 301 managing a conversation between a user and a computer system according to an embodiment of the present invention. The user may be a person who wants to find a machine resource using the computer system. The computer system may correspond to computer system 101 described in FIG. 1.

Display 301 may be connected to computer system 101 through a display cable or a separate computer to which display 301 is connected. The separate computer may be connected to computer system 101 via a network such as an internet or an intranet.

First, the computer system may display, on display 301, a message prompting input of a search query for finding a machine resource. The search query may be an input in a natural language form. For example, the message prompting input of a search query for finding a machine resource is displayed in balloon 311 as follows: “We will present machine resources in technical fields to you. What type of machine resources are you searching for?”

In response to the display of the message in balloon 311, the user may input, using a keyboard, a mouse, a touch pen or a finger of the user, or speech input method, a search query for finding a machine resource. In one example, the search query from the user is displayed in balloon 312 as follows: “Machine resources having a capability for answering technical questions relating to Projection TTTYYY.”

In response to the input of the search query from the user, the computer system receives the search query from the user.

One example of the received search query is shown in block 321 as follows: “Machine resources having a capability for answering technical questions relating to Projection TTTYYY.”

The computer system extracts words from the search query in block 321 using morphological analysis. In one example, by using morphological analysis, the computer system may cut out words and carry out parsing in a received search query. It will be apparent to one skilled in the art that any known computer-implemented methods for morphological analysis can be used for extracting words from the search query. It will be apparent to one skilled in the art that one or more different types of analysis may be implemented to extract words from search queries in one or more different types of forms.

In one example, the extraction of words from the search query in block 321 is shown in block 322. Block 322 shows that the extracted words are as follows: “machine resources”, “capability”, “answering”, “technical questions”, and “Projection TTTYYY”.

After the extraction of the words from the search query, the computer system assigns categories to the words using a dictionary 361. In one example, the one or more extracted words to which categories have been assigned in block 323 may be the one or more first words.

The computer system may use dictionary 361 as a keyword dictionary as explained below. The keyword dictionary may comprise pairs of word and a category associated with this word. Words in the keyword dictionary may be words relating to the finding of a machine resource, for example common or specific words used in search queries. Categories in the keyword dictionary may be categories which can be assigned to a skill word or an inquiry word in words extracted from the search query. The aforesaid embodiment of the keyword dictionary is also applicable to dictionary 361.

If a word among the extracted words in block 322 is not found in dictionary 361, the computer system may assign a category “unknown word” to this word. Alternatively, the computer system may not assign any category to this word. In this alternative embodiment, any category is not assigned to this word.

In one example, block 323 illustrates an assignment of categories to the extracted words in block 323, shown as follows: “machine resources”—“inquiry”; “capability”—“inquiry”; “answering”—“inquiry”; “technical questions”—“skill”; and “Projection TTTYYY”—“unknown word”. In the example in block 323, the category “unknown word” was assigned to the word “Projection TTTYYY”, because dictionary 361 does not have the word “Projection TTTYYY”.

The computer system examines whether there is an unknown word in the extracted words or not. If the word to which a category “unknown word” was assigned is found, the computer system chooses this word as an unknown word 324. Alternatively, if the computer system finds a word to which any category was not assigned, the computer system chooses this word as unknown word 324.

With reference now to FIG. 3B, in one example, the computer system may search for unknown word 325 on a repository such as a machine resource database 371. In one example, machine resource database 371 may have pairs of machine resource data and skill information associated with the machine resource data.

If unknown word 325 is not found on machine resource database 371, the computer system then searches for unknown word 326 on a net 381. Net 381 may be a network such as an internet or an intranet. Net 381 may be a dictionary on the network, such as an internet dictionary or an intranet dictionary.

A process performed if unknown word 325 is found on machine resource database 371 will be separately explained by referring to FIG. 3D below.

If unknown word 326 is found on net 381, the computer system obtains a description on a page on the net on which page the unknown word is found, as seen in the found page 382 shown in FIG. 3B. Page 382 may have header and a description. The header may comprise a title. The description may be explanatory notes on the header. Page 382 shows the header as a title of the descriptions and a description relating to the title. Page 382 may have the title “Projection TTTYYY” and the description “The game machine sold by ZZZ whose head quarters reside in Tokyo.”

The computer system may extract words from the description in page 382 using the aforesaid morphological analysis.

Block 328 illustrates one example of the extraction of words from the description in page 382. Block 328 shows that the extracted words are as follows: “game machine”, “sold by” “ZZZ”, “head quarters”, “reside” and “Tokyo”.

After extracting the words from the description, where the one or more extracted words from the description may represent the one or more second words, the computer system may assign categories to the second words using a dictionary 362.

For dictionary 362, the computer system may use dictionary 361, such as the aforesaid keyword dictionary, the aforesaid system dictionary as explained below, or a combination thereof. If the dictionary comprises the aforesaid keyword dictionary and the aforesaid system dictionary, the assignment of categories to the words using the dictionary is done in the order of the keyword dictionary and then the system dictionary.

The aforesaid explanation of the keyword dictionary and the system dictionary is applicable here.

With reference now to FIG. 3C, one example of the assignment of categories is shown in block 329 in FIG. 3C as follows: “game machine”—“skill”, “ZZZ”—“proper noun”, “head quarters”—“noun”, and “Tokyo”—“proper noun”.

The computer system finds, among the second words in block 329, a word to which a predetermined category was assigned. The predetermined category may be determined depending on the purpose of the finding of resources. The predetermined category may be a category representing a skill of a machine resource.

In one example, as illustrated in FIG. 3C, the predetermined category is “skill”. In the example in FIG. 3C, the word “game machine” is chosen among the second words in block 329.

Thereafter, the computer system extracts a word which may represent the correlation word, having a high correlation with the found word. The explanation of the correlation is applicable here.

With reference now back to FIG. 3C, the correlation word of the word “game machine” is “game programming” according to the correlation value as seen in table 391. Accordingly, the computer system regards the word “game programming” as a correlation word in block 331. Multiple words can be chosen as correlation words, if multiple words as correlation words exist.

The computer system may find, among the first words, a word to which a category that is the same as the aforesaid predetermined category was assigned, referred to as “a search word” in block 331. Multiple words may be chosen as search words, if multiple words as search words exist.

In one example, illustrated in FIG. 3C, the predetermined category is “skill”. In this case, the word “software development” is chosen among the first words in block 323.

Thereafter, the computer system finds, from a repository such as machine resource database (DB) 371, machine resource data using the correlation word “game programming” and the search word “software development” in block 331. The computer system may find human resource data using only the correlation word, only the search word and both of the correlation word and the search word and, then, gives priority to each found human resource data using a mining method as described below.

Machine resource database 371 may have pairs of an ID of a machine resource (ID), status of the machine resource (Status), and specification information on the machine resource (Specification). The status may be represented as follows: 1. Dispatched; 2. Waiting for being dispatched; and 3. Under repair or scrapped. The specification information may comprise, for example, but not limited to, job history, performance, or fee for sale or rental.

As a result, the computer system obtains one or more machine resource data entries from among the entries illustrated at reference numeral 372, from machine resource database 371, with or without a value such as a recommended value or a mining analysis value.

In one example, a career field may contain both “game machine (skill)” and “software development (skill)”

When the computer system obtains machine resource data, the computer system may further use a mining method using a correlation related to experience levels.

The aforesaid example of the correlation related to experience levels in the example in FIGS. 2A-2C is applicable here in the example in FIGS. 3A-3D.

With reference now back to FIG. 3C, an embodiment of the obtained machine resource data is shown in block 332 as follows: “#004” ( %); “#002” ( %)”; . . . ”.

Thereafter, the computer system or the display presents the found machine resource data to the user, as seen in balloon 313. In one example, balloon 313 is illustrated as follows:

“The following bots are recommended:

ID #00C ( %)

ID #00B ( %)

. . . ”.

The computer system may list the found machine resource data according to the order of priority. The computer system may present the listed human resource data to the user. Alternatively, the display may display the listed human resource data to the user.

If the user wants to know more details about the presented machine resource, the user can click the characters of the presented machine resource data on display 303.

In response to the click, the computer system may obtain detailed information on the presented machine resource data from machine resource database 371 in order to display the information on display 303.

With reference now to FIG. 3D, in one example, machine resource database 391 is used instead of machine resource database 371 and machine resource database 391 has the word “Projection TTTYYY” in the item “Specification”.

If the unknown word is found on machine resource database 391, the computer system then finds, from machine resource database 391, machine resource data using the unknown word or the unknown word and the aforesaid search word.

As a result, the computer system obtains one or more machine resource data entries from among the entries illustrated at reference numeral 373 in machine resource database 391, with or without a value such as a recommended value or a mining analysis value.

One example of the obtained machine resource data is shown in block 341 as follows: “#00C” ( %); “#00B” ( %)”; . . . ”.

Thereafter, the computer system or the display presents the found machine resource data to the user, as seen in balloon 314. One example of balloon 314 is as follows:

“The following bots are recommended:

ID #00C ( %)

ID #00B ( %)

. . . ”

The computer system may propose that the unknown word be added to dictionary 361 if the unknown word is in the repository, but not currently in dictionary 361.

According to the examples in the block diagrams described in FIGS. 3A to 3C, an advantage of one or more embodiments of the present invention is that where the unknown word is not found on the repository, such as a machine resource database 371, but is found on the net, the computer system may use the aforesaid correlation word instead of an unknown word and, therefore, may present a suitable machine resource in response to a natural language input that even contains an unknown word.

According to the block diagram described in FIGS. 3A, 3B and 3D, an advantage of the one or more embodiments of the present invention is that if the unknown word is found on the repository, the computer system may, using this unknown word, present a further suitable machine resource in response to a natural language input that even contains an unknown word.

An embodiment of the examples described in FIGS. 2A to 2C and FIGS. 3A to 3D may be combined to find either a human resource data or a machine resource data from a repository that comprises pairs of human resource data and skill information associated with the human resource data together with pairs of machine resource data and skill information associated with the machine resource data.

FIGS. 4A and 4B and FIGS. 6A and 6B illustrate different high level logic flowcharts each depicting examples of a process and computer program for finding a human or machine resource. FIGS. 5A to 5C and FIGS. 7A to 7C illustrate different high level logic flowcharts each depicting examples of a process and computer program for finding a worksite for a human or machine resource.

At step 406, the computer system examines whether there is an unknown word in the extracted words. At step 406, if there is an unknown word in the extracted words, the computer system proceeds to step 411. Meanwhile, if there are not any unknown words in the extracted words, the computer system proceeds to step 407.

At step 407, the computer system finds, from a repository 471, such as a human resource database or a machine resource database, human or machine resource data using the first word to which a predetermined category was assigned. If there are multiple first words, the multiple first words are used to find human or machine resource data.

At step 411, the computer system searches for the unknown word on a net, such as an internet or intranet.

At step 412, the computer system examines whether the unknown word is found on the net. The net may be a network such as an internet or an intranet. The computer system may use a dictionary on the net, such as internet dictionary or an intranet dictionary. At step 412, if the unknown word is found on the net, the computer system proceeds to step 413. Meanwhile, if the unknown word is not found on the net, the computer system proceeds to the aforesaid step 407.

At step 413, the computer system obtains a description on a page on the net on which page the unknown word is found. The page may have a header and a description. The header may comprise a title. The description may be explanatory notes on the header.

At step 414, the computer system extracts words from the description using morphological analysis. The morphological analysis used in step 414 may be the same or different morphological analysis used in step 404.

At step 415, the computer system assigns, using a dictionary 462, categories to the words extracted from the description. The one or more words to which categories are assigned may represent the one or more second words. The dictionary used in step 415 may be the aforesaid keyword dictionary or the aforesaid keyword dictionary and system dictionary.

At step 416, the computer system finds, among the second words, a word to which a predetermined category was assigned and then extracting a word having a high correlation with the found word, which may present a correlation word. The predetermined category is a category representing a skill of a human or machine resource. Further, the computer system finds, among the one or more first words, a word to which a category which is the same as the aforesaid predetermined category was assigned, which may represent a search word.

At step 417, the computer system finds, from a repository 471, human or machine resource data using the correlation word and the search word. Repository 471 may be the aforesaid human resource database or the aforesaid machine resource database.

At step 418, the computer system lists the found human or machine resource data so as to enable the found human or machine resource data to be presented on the display to the user. Thereafter, the computer system presents the listed human or machine resource data to the user. Alternatively, the display displays the listed human or machine resource data to the user.

At step 419, the computer system terminates the process mentioned above.

According to the flow chart diagram described in FIGS. 4A and 4B, the computer system uses the aforesaid correlation word instead of an unknown word and, therefore, can present a suitable human or machine resource to a natural language input that even contains an unknown word.

With reference now to FIGS. 5A to 5C, FIGS. 5A to 5C are flowcharts depicting a process of finding a human or machine resource, in accordance with one embodiment of the present invention.

At step 501, the computer system starts the process mentioned above.

Steps 502 to 507 may correspond to steps 402 to 407, respectively. Accordingly, detailed explanations of steps 502 to 507 are omitted here.

At step 508, the computer system searches for the unknown word on repository 571 such as the aforesaid human resource database or machine resource database.

At step 509, the computer system examines whether the unknown word is found on repository 571. If a unknown word is found on repository 571, the computer system proceeds to step 510. Meanwhile, if the unknown word is not found on repository 571, the computer system proceeds to step 511.

At step 510 after the aforesaid step 509, the computer system finds, from repository 571, human or machine resource data using the unknown word which was found on the repository or this unknown word and the one or more first words to which a predetermined category was assigned.

Steps 511 and 512 may correspond to steps 411 and 412, respectively. Accordingly, detailed explanations of steps 511 and 512 are omitted here.

At step 510 after the aforesaid step 512, the computer system finds, from repository 571, human or machine resource data using the one or more first words to which a predetermined category was assigned.

Steps 513 to 518 may correspond to steps 413 to 418, respectively. Accordingly, detailed explanations of steps 513 to 518 are omitted here.

At step 519, the computer system terminates the process mentioned above.

In an optional step 520, the computer system may propose that the unknown word is to be added in the dictionary if the unknown word is in the repository such as in step 509. Therefore, later in this step 520, the dictionary has the aforesaid unknown word as the known word registered in the dictionary.

According to the flow chart diagram described in FIGS. 5A to 5C, the computer system uses the aforesaid correlation word instead of an unknown word and, therefore, can present a suitable human or machine resource in response to a natural language input that even contains an unknown word.

With reference now to FIGS. 6A and 6B, FIGS. 6A and 6B are flowcharts depicting one example of a process of finding a worksite for a human or machine resource, in accordance with an embodiment of the present invention.

At step 601, the computer system starts the process mentioned above.

At step 602, the computer system displays, on a display, a message prompting input of a search query from a user. The search query may be for finding a worksite for a human or machine resource.

At step 606, the computer system examines whether there is an unknown word in the extracted words. If there is an unknown word in the extracted words, the computer system proceeds to step 608. Meanwhile, if there is not an unknown word in the extracted words, the computer system proceeds to step 607.

At step 607, the computer system finds, from a repository 671, such as a worksite database, a worksite data using the first word to which a predetermined category was assigned. If there are multiple first words, the multiple first words are used to find a worksite data.

At step 611, the computer system searches for the unknown word on a net, such as an internet or intranet.

At step 612, the computer system examines whether the unknown word is found on the net. The net may be a network such as an internet or an intranet. The computer system may use a dictionary on the net, such as internet dictionary or an intranet dictionary. If the unknown word is found on the net, the computer system proceeds to step 613. Meanwhile, if the unknown word is not found on the net, the computer system proceeds to the aforesaid step 607.

At step 613, the computer system obtains a description on a page on the net on which page the unknown word is found. The page may have a header and a description. The header may comprise a title. The description may be explanatory notes on the header.

At step 614, the computer system extracts words from the description using morphological analysis. The morphological analysis used in step 614 may be the same or different morphological analysis used in step 604.

At step 615, the computer system assigns, using a dictionary 662, categories to the words extracted from the description. The one or more words to which categories are assigned may represent the one or more second words. The dictionary used in step 615 may be the aforesaid keyword dictionary or the aforesaid keyword dictionary and system dictionary.

At step 616, the computer system finds, among the second words, a word to which a predetermined category was assigned and then extracting a word having a high correlation with the found word, which may represent a correlation word. The predetermined category is a category representing a skill to be required for a worksite for a human or machine resource. Further, the computer system finds, among the first words, a word to which a category that is the same as the aforesaid predetermined category was assigned, which may represent a search word.

At step 617, the computer system finds, from repository 671, a worksite data using the correlation word and the search word. Repository 671 may be the aforesaid worksite database.

At step 618, the computer system lists the found human or machine resource data so as to enable the found human or machine resource data to be presented on the display to the user. Thereafter, the computer system presents the listed human resource data to the user. Alternatively, the display displays the listed human resource data to the user.

At step 619, the computer system terminates the process mentioned above.

According to the flow chart diagram described in FIGS. 6A and 6B, the computer system uses the aforesaid correlation word instead of an unknown word and, therefore, can present a suitable worksite to a natural language input that even contains an unknown word.

With reference now to FIGS. 7A to 7C, FIGS. 7A to 7C are flowcharts depicting one example of a process of finding a worksite for a human or machine resource, in accordance with another embodiment of the present invention.

At step 701, the computer system starts the process mentioned above.

Steps 702 to 707 may correspond to steps 602 to 607, respectively. Accordingly, detailed explanations of steps 702 to 707 are omitted here.

At step 708, the computer system searches for the unknown word on a repository 771 such as the aforesaid worksite database.

At step 709, the computer system examines whether the unknown word is found on repository 771. If the unknown word is found on repository 771, the computer system proceeds to step 710. Meanwhile, if the unknown word is not found on repository 771, the computer system proceeds to step 711.

At step 710 after the aforesaid step 709, the computer system finds, from repository 771, worksite data using the unknown word which was found on the repository or this unknown word and the one or more first words to which a predetermined category was assigned.

Steps 711 and 712 may correspond to steps 611 and 612, respectively. Accordingly, detailed explanations of steps 711 and 712 are omitted here.

At step 710 after the aforesaid step 712, the computer system finds, from repository 771, human or machine resource data using the one or more first words to which a predetermined category was assigned.

Steps 713 to 718 may correspond to steps 613 to 618, respectively. Accordingly, detailed explanations of steps 713 to 718 are omitted here.

At step 719, the computer system terminates the process mentioned above.

In an optional step 720, the computer system may propose that the unknown word is to be added in the dictionary if the unknown word is in repository, such as in step 709. Therefore, later in this step 720, the dictionary has the aforesaid unknown word as the known word registered in the dictionary.

According to the flow chart diagram described in FIGS. 7A to 7C, the computer system uses the aforesaid correlation word instead of an unknown word and, therefore, can present a suitable worksite to a natural language input that even contains an unknown word.

FIGS. 9A and 9B show one example of a different overall functional block diagram in accordance with an embodiment of the present invention.

With reference now to FIG. 9A, FIG. 9A is an overall functional block diagram of depicting one example of a computer system hardware in relation to the process of FIGS. 4A and 4B and FIGS. 6A and 6B, in accordance with an embodiment of the present invention.
